Answer

The solution to the equation is \(x = -12.89\).

Explain

## Step 1: <br />First, we need to isolate the cubic term on one side of the equation. To do this, we add 1 to both sides of the equation. This gives us:<br /><br />### \(-41 + 1 = 5(x+11)^3 \)<br /><br />## Step 2: <br />Next, we divide both sides of the equation by 5 to further isolate the cubic term. This gives us:<br /><br />### \( \frac{-40}{5} = (x+11)^3 \)<br /><br />## Step 3: <br />Now, we take the cube root of both sides to solve for \(x+11\). This gives us:<br /><br />### \(\sqrt[3]{-8} = x+11 \)<br /><br />## Step 4: <br />Finally, we subtract 11 from both sides to solve for \(x\). This gives us:<br /><br />### \(x = \sqrt[3]{-8} - 11 \)
